Well, it looks like we may never have our own Jurassic Park. Scientists at the University of Manchester failed to pull DNA samples from insects trapped in 10,600 year-old amber, leading them to conclude that the chances of extracting intact DNA from samples millions of years older is likely impossible.

For those living in a paleolithic-era cave, the dinosaurs in Spielberg's 1993 classic, Jurassic Park, were spawned from DNA samples taken from amber-trapped ancient insects engorged with dinosaur blood. It's a fascinating idea, but unfortunately — or fortunately, depending on your opinion of dinosaurs — it's probably not gonna happen.

I read an article about scientists trying to reverse engineer dinosaurs from modern birds, the article explained that a modern chicken's genome still has the code to produce features like teeth and a tail, that code simply wasn't active and scientist used to think it was just a bunch of junk code left over.

So basically they could activate the unused code in a bird and get a dinosaur, the amber extraction they said was like extracting DNA from fossilized bones, there's simply no DNA to extract.
